By means of a projection apparatus the application of the methods of chemical microscopy to the teaching of general chemistry were illustrated. The simpler types of equipment necessary were shown. The use of the optical methods were shown in the teaching of such things as allotropy and transition temperatures, formation of stable and unstable double salts, formation of solid solutions, eutectics, etc., tests for purity and tests for identity. The teaching of important optical properties of matter by means of simple polarization apparatus was demonstrated.
